Strap for Museum Collection N° 1 "Pilots 1938" Aquarella Blue Sapphires

The Omega Museum Collection 5772.71.56 features a 24-millimeter lug width. This precise measurement is the fundamental parameter for selecting compatible straps and ensuring proper fit between the metal lugs of the case.

Natural alligator is the most coherent choice with the Museum Collection aesthetic, thanks to its geometric and discreet grain. For greater versatility over time, vegetable-tanned calf develops a rich patina; shell cordovan offers instead a natural luster that ages magnificently toward amber tones.

Use a spring bar tool to loosen the clasps present on the sides of the lugs. Insert the tool into the groove of the clasp, apply light pressure to release the pin, then remove the old strap. Position the new strap by aligning the holes and reinsert the pin until the safety click.

Yes, provided the width is exactly 24 millimeters. Many generic straps available online are sized for different lug widths (22mm, 26mm). Always verify the measurement before purchase and choose specialized manufacturers that guarantee technical compatibility and construction quality.

Duration depends on daily use and maintenance. A quality artisanal leather strap on a regularly worn watch has an average lifespan of 3-5 years before requiring replacement. Vegetable-tanned leather tends to last longer than quick-tanned leather; shell cordovan is particularly resistant to wear over time.
